SPECIFICATION forming part of Letters Patent No. 642,611, dated February6, 1900.

Application filed J'une 2311899- Serial No. 721,649. (No model.)

To to whom, it may concern:

Be it known that I, FRIEDRICH KAISER, a subject of the Emperor ofGermany, residing at St.Johann-upon-Saar, Germany,have made certain newand useful Improvements in Appliances for Molding Truss-Heads, of whichthe following is a specification.

My invention is a molding appliance adapted to be placed upon the bodyof the person afflicted with hernia andv to render it possible to get anexact impression of that part of the body at the hernia, so that atruss-pad may be formed to fit accurately the body at the hernia to keepit in position.

In the drawings, Figure 1 is a side view of the appliance, and Fig. 2 aplan View of the same.

The device comprises a mold a open upon its opposite sides andcomprising a shell forming a body wider at one end, as shown in the planview, than at the other. This shell is adapted to be placed upon thebody of the person so as to surround the parts where the hernia exists.For this purpose the contacting edge of the shell is beaded or turnedover to provide a comfortable bearing-surface against the body, and thisbeaded seat is curved to conform approximately to the surface of thebody. A presser-plate 0 moves in the shell, and this is operated by ascrew b,

which is held by a shackle or hook d, removably held to the shell by thepin f. A spring g serves to hold the mold to the body, and when the moldis adjusted into place it is filled with the plastic, material, and thenby operating the plate 0 the material is forced against the body andconforms accurately to the surface thereof. The material sets rapidly,and by using this mold ed body the head for the truss may be formed inany well-known way. The hollow molds varyin size and shape.

I'claim- 1. A molding device consisting of a shell having an edgeconforming approximately to the surface of the body and having an openinterior and open ends, and a pressing-plate with means for moving saidplate in the shell, substantially as described.

2. A molding device comprising the shell having an edge to bear on thebody, a pressing-plate movable in said shell, a screw for operating theplate and a hook d detachably secured to the shell, substantially asdescribed.

In witness whereof I have hereunto set my hand in presence of twowitnesses.

FRIEDRICH KAISER.
